CD74HC4543E LCD Driver Power Management IC 16-PDIP

The CD74HC4543E is an LCD driver IC Designed for Driving 7-segment liquid crystal displays (LCDs) in digital systems. It functions as a BCD-to-7-segment decoder/driver, converting a 4-bit binary-coded decimal (BCD) input into the signals needed to drive a 7-segment LCD. The IC is specifically optimized for low-power LCD applications and supports a wide range of display configurations with its integrated backplane (BP) output. Part of the HC (High-Speed CMOS) family, the CD74HC4543E operates with low power consumption and high noise immunity. It features a wide supply voltage range of 2V to 6V, making it compatible with a variety of logic families. Its outputs are capable of directly driving the segments of an LCD, while an additional BP pin provides the backplane signal required for proper LCD operation. Housed in a 16-pin PDIP (Plastic Dual In-line Package), the IC is well-suited for through-hole mounting in compact or simple circuit designs.
